Conflicts are an inevitable phenomenon within organizations. The organization of interest in this study is the elementary school and the conflicts that may emerge into its context. There are many types of conflicts and their consequences vary; there are positive consequences, but also negatives ones. When teachers are to express their opinions on conflicts, they think that conflicts happen often enough, and they recognize both their negative and positive effects. The present study examined teachers’ perceptions on the frequency of certain types of school conflicts and their consequences. The researchers asked teachers working in public elementary schools in Achaia Prefecture, Greece. Personal characteristics of the study’s participants such as age, gender, years in service and teaching specialization were also taken into consideration. It was found that a small percentage of teachers believed that conflicts happen very often. In general, teachers thought that negative consequences are more frequent than positive ones, even though, they recognized the beneficial aspect of conflicts. Lastly, the teachers’ groups that were formed based on participants’ characteristics showed significant differences. Study’s limitations along with suggestions for future research are also discussed.

This research aims to describe the expectations of prospective teachers for students' mathematical thinking processes in solving problem-based on the Polya model. This model is perceived by the theory of mathematical thought processes proposed by Mason. A descriptive method with a qualitative approach was used in this research. The research subjects were 25 students from the Department of Mathematics Education, Ibrahimy University. The test was given to collect data related to mathematical thinking processes expected by prospective teachers to students. Collected data including observations, tests, and interviews were tested in the aspect of their validity by triangulation. The qualitative descriptive was used to analyze the data. The results indicated that: (1) The average GPA (Grade Point Average) of the high, medium, and low group prospective teachers' were 93.25; 89.89; and 83.63 with a standard deviation of 1.754 each; 1.054; and 5.370, respectively (2) The prospective teachers expected that the students' mathematical thinking processes were able to carry out all of four mathematical thinking processes based on Mason Theory; (3) The prospective teachers expected that students were able to use Mason Theory on every stage of the Polya model problem solving; and (4) The expectation of prospective teachers were specializing (89%), generalizing (75%), conjecturing (62%), and convincing (59%). The results suggest for following up in a teachers or lecturer’s meeting in order to find out the expectations of their students' mathematical thinking processes, both in mathematics or other disciplines.
